This is a question written in my book, i tried to solve it but didnt work with me.

Homework Statement


A power station delivers a power of 150kW to small town at 15km from the station. Energy is transmitted by means of a transmission line of total resistance of 0.6 _()_ (ohm). The power factor is 1. Calculate the power lost as a result of this transmission at a voltage of 240V.
It is in the lesson of transformers.

Homework Equations





The Attempt at a Solution


I have the rule that the power lost is equal to : [R(line)*(P2)^2]/[(Veff)^2 * cos^2(phi2)
or R(line) * (I2eff)^2 , but i dont have the I2eff and neither do i have P2 nor cos(phi)
